Hi,
I'm working at a very small electronics assembly firm and we need to get a better thermal profile of our reflow and solder wave ovens. Our firm is part of a larger firm that was set up to help handicapped people find work in the Netherlands. You could hardly call us professionals (don't tell my boss I said so) and all calibrations are nowadays done by an external firm since we can't afford the right equipment.
As electronics- and programming- hobbyist I'm busy developing a microcontroller-board to read thermocouples and an accelerometer. Probably not as good as the commercial version, but at least we could check ovens every day in stead of every month and electronics available look very promising.
Since the logger will travel through the oven I need to insulate it as much as possible. I did touch the commercial logger (Mole), which uses rubber as insulation. I felt no difference in temperature before and right after it's journey.
So far I'm just starting to know a little about thermal conductivity, isolation and different kinds of rubber. By now I guess (Fluor-)silicone rubber was used, both massive and open cell structure. But, as former grounds-keeper/assistant on a school for kids aged 4-12, I could use some help getting my nose in the right direction(s) in order to find the best insulation possible.
If you should know more, perhaps know a factory/shop specializing in this kind of insulation/ specialized sites/forums etc etc, you would make me (and probably our clients) very happy.
Best wishes,
Bart.
